MZ1系列

Product introduction: 当电路处于正常状态时,通过PTC的电流小于额定电流,PTC处于常态,阻值很小,不会影响被保护电路的正常工作。当电路出现故障,电流大大超过额定电流时,PTC陡然发热,呈高阻态,使电路处于相对"断开"状态,从而保护电路不受破坏。当故障排除后,PTC亦自动回复至低阻态,电路恢复正常工作。选用PTC热敏电阻器作为过载保护元件,首先确认线路最大正常工作电流(就是PTC热敏电阻器的不动作电流)和PTC热敏电阻器安装位置(正常工作时)最高环境温度、其次是保护电流(就是PTC热敏电阻器的动作电流)、最大工作电压、额定零功率电阻,同时也应考虑元件的外形尺寸等因素。
面料: MZ1系列PTC热敏电阻器是一种对异常温度及异常电流自动保护、自动恢复的保护元件,俗称"自复保险丝""万次保险丝"。
类别:
型号:

用于通用线路过流、过载保护,例如变压器、微电机、开关电源、充电器、适配器、仪器、仪表、电子线圈、控制面板、家用电器、空调、微波炉等的过流、过载、短路保护。
